Background of Istanbul’s Transit Expansion Projects
Istanbul has been actively expanding its transit infrastructure over the past decade, including new metro lines, tramways, and bus rapid transit systems. The Northern Railway project is part of this broader strategy to address increasing urban population and traffic challenges.
Previous projects, such as the Marmaray and new metro lines, have significantly improved connectivity across the city, but demand continues to grow.
